Embodiment 1

[0025] refer to figure 1 , which shows a flowchart of a method for adjusting screen brightness according to an embodiment of the present invention, which is applied to a mobile terminal, and the method may specifically include the following steps:

[0026] Step 110, when the mobile terminal is in a bright screen state, identify the face information of the current user of the mobile terminal.

[0027] In the embodiment of the present invention, the face information of the current user of the mobile terminal may be identified based on any available device or method, which is not limited in the embodiment of the present invention. For example, a preview image containing a face pattern may be obtained based on the front camera, and then face recognition is performed based on the preview image, and the face pattern in the preview image is acquired as face information. Facial information may include but not limited to facial pattern, facial identification, etc. Specifically, the sp...

Embodiment 2

[0039] refer to figure 2 , which shows a flow chart of a method for adjusting screen brightness according to another embodiment of the present invention, which may specifically include the following steps:

[0040] Step 210, when a manual adjustment operation on the screen brightness value of the mobile terminal is received, obtain the screen brightness value and face information corresponding to the manual adjustment operation.

[0041] As mentioned above, the mobile terminal itself has been set with a default brightness adjustment strategy when it leaves the factory, and the default brightness adjustment strategy includes a default mapping relationship between screen brightness values ​​and light brightness values. Moreover, if the current user of the mobile terminal does not set a corresponding brightness adjustment policy, then the mobile terminal will adjust the screen brightness according to the default brightness adjustment policy. If the user is not satisfied with the s...

Embodiment 3

[0076] refer to image 3 , shows a block diagram of a mobile terminal according to an embodiment of the present invention. The mobile terminal in the embodiment of the present invention can realize the details of the method for adjusting the screen brightness in the first embodiment to the second embodiment, and achieve the same effect. image 3 The illustrated mobile terminal 300 includes:

[0077] The face information identification module 310 is configured to identify the face information of the current user of the mobile terminal when the mobile terminal is in a bright screen state.

[0078] The brightness adjustment policy acquisition module 320 is configured to acquire a brightness adjustment policy matching the face information based on the face information, and the brightness adjustment policy includes: a mapping relationship between light brightness values ​​and screen brightness values.

[0079] The screen brightness adjustment module 330 is configured to acquire t...

Abstract

The embodiment of the invention provides a screen brightness adjustment method and a mobile terminal. The method comprises the following steps: when the mobile terminal is in a bright screen state, identifying the face information of the current user of the mobile terminal; based on the face information, a brightness adjustment strategy matched with the face information being obtained. The brightness adjustment strategy includes: a mapping relationship between a light brightness value and a screen brightness value; a light brightness value of the environment in which the mobile terminal is currently located is obtained, and a screen brightness value of the mobile terminal is adjusted based on the brightness adjustment strategy. The invention improves the adjustment efficiency of the screenbrightness and the visual effect of the user by acquiring the brightness adjustment strategy satisfying the visual requirement of the current user according to the face information of the current user.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a screen brightness adjustment method and a mobile terminal. Background technique [0002] At present, mobile terminals such as mobile phones and computers generally have an inductive sensor for ambient light, referred to as light sensor, which can inform the mobile terminal of the light brightness value of the current environment. The brightness value of the mobile terminal screen will be automatically adjusted according to the signal of the light sensor. In the prior art, the mapping relationship between the screen luminance value and the light luminance value is generally a factory default. However, considering that the sensitivity of each user's eyes to screen brightness is different, mobile terminals generally allow users to manually modify the mapping relationship between screen brightness values ​​and light brightness values. [0003] However, when the same mob...
